UNIVERSAL CALL-CIRCUIT AND APPARATUS FOR TOLL SERVICE.

SPECIFICATION forming part Of Letters Patent N0. 685,401, dated October29, 1901. Application filed June 27,1901. Serial No. 66,258. (No model-lTo all whom it may concern:

Be it known that I, ANGUS S. HIBBARD, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain Improvements inUniversal Call-Circuits and Apparatus for Toll Service, of which thefollowing is a specification.

This invention relates to telephone exchange or long-distancecentralstation switchboard apparatus, and particularly concernsappliances for conveying between different switchboards instructionsregarding the interconnection of substation-lines with lines leading toother central stations belonging to other exchanges. R

A telephone-exchange organized for the transaction of the telephonebusiness of a large city may comprehend several independent centralstations serving different districts of such city, the substation-linesof each district converging to their own particular central station,Where they connect with a switchboard by means of which they may beinterconnected among themselves. There are also city trunk-circuitswhereby the substation-lines primarily belonging to each central stationmay be interconnected when desired with those of any other centralstation. A very considerable part of the work of such atelephone-exchange is, however, attributable to the interchangeof'business between its substations and the substations of neighboringexchanges and the establishment by means of appropriate switchingapparatus and interconnecting lines of through intercommunication,whereby for the transaction of such business the substations ofdifferent or distinct exchanges may engage directly in conversation. Thebusiness between the stations of any two such distinct exchanges as, forexample, between Boston and Lowell or between Chicago and Evanstonisknown as toll business, and the lines extending between them are termedtoll-lines. For the transaction of toll business it has been foundconvenient to establish a special tollline switch-station which may be asegregated section of a general operating-room or preferably anindependent switch-room. This tollstation, again, may be in the samebuilding with some particular one of the regular central stations, or,if desired, may be in any convenient place separate from all. At each ofthe said regular central stations there is ordinarily in addition to thegeneral switchboard a trunk-line switchboard whereon each of the severalsubstation-lines of such central station has a switch-socket whereby thesaid lines may be switched to any desired trunk, or instead of a specialboard a portion of the general board may be devoted to this part of thework. Trunk-lines extend between these trunk-line boards or sections ofthe several central stations of the exchange to the switch board at thetoll-station, and the toll-lines extend between the latter and thecentral stations of other and outside exchanges. Moreover, there isprovided an order or instruction circuit from the toll-station to thetrunk-operators position at each central station of the home exchangeand also an order or instruction circuit from the severalanswering-operators positions of each central station to the switchboardat the toll-station.

Toll connections or toll-messages require special attention and care onthe part of the operating force of the central station or the severalcentral stations concerned, and a special charge is made for them. Theconditions of practice render it necessary that the names andtelephone-numbers of the calloriginating and called-for substations,together with information as to the date, the time of day, andultimately the time consu med in the exchange of conversation or thetransmission of the message, shall be entered on a blank form termed theticket. This isdone, first, to avoid the confusion and liability toerror,which,as experience has shown,

is apt to occur if the above-recited information be transmitted orallybetween the several operators, and, second, to furnish a rec- 0rd of thetransaction for future reference.

In the toll business of exchanges as heretofore practiced agenerally-adopted plan or ar- 5 rangement for handling toll connectionshas been the following: The operator in an exchange central stationreceiving a call from a substation for a substation in another exchangewould by a call-wire 0r order-circuit announce the call to an operatorat the tollswitchboard or toll-station end of said ordercircuit, statingthat a certain-numbered line desired a toll connection, and thetoll-station operator was required to note the number of saidcalling-line on a ticket and pass the ticket to a second toll-stationoperator known as the recording operator. This recording operator thenwould call for the line noted on the ticket and ascertain from thesubstation desiring communication the necessary details, such as thename and number of the person wanted, &c., then instructing the personwho gave the call to hang up his telephone for the present, and statingthat he would be notified when the connection of the several toll andother lines was complete. The recording operator then passed the ticketto a third toll-room or toll-station operator, whose business it was tosecure con nection, first,with the distant exchange, and, second, withthe desired substation at such exchange, and this passing of the tickethas been accomplished in several ways-for example, by messenger, by amoving belt-line, or by pneumatic tube-and finally when the toll-lineoperator had reached the distant station wanted and had securedcommunication therewith she would again call the originating substationand switch the lines together. The operation thus carried out requiresthe services and passes through the hands of three or more operators inthe toll-room.

The object of my present invention is to enable a single operator totake entire charge of each message passing through the tollroom and tocarry out the various snboperations concerned in the establishment ofthe connection, thereby expediting the service, dispensing with thenecessity of circulating the ticket, minimizing the chance of error, andin case of error readily determining the responsibility therefor. Forthe attainment of this object I provide that the order or instructioncircuit extending from each central station to the toll-station (overwhich orders for toll connections are transmitted by the answeringcentral-station operators) shall at its receiving end atsaid-toll-station be associated with the telephones of a group of two ormore operators, and a circuitchanger or switch capable of being placedin either of three positions and of determining by its position therelation of the order-circuit and the several telephones of the group,the reciprocal relation of the several members of such group and therelation of the several groups to the several order-circuits. Theseveral telephones of each group are placed each in a correspondingloop, and the order-circuit may be regarded as being provided with anextension, whereby after reaching the switch of the first operatorstelephone it is continued to the several other telephone-loopssuccessively and through a series of separable contacts, the switch ofeach loop controlling the connection with the order-circuit not only ofits own loop and telephone, but also of all following loops of thegroup. Each switch by its three positions, respectively, may connect itsown telephone fully in the order-circuit, disconnecting all followingtelephones of the group and the loops containing them, may whollydisconnect its own loop and telephone from the order-circuit, leavingthe said circuit continuous as far as it is concerned to all followingtelephones of the group, or may bridge its telephone across theorder-circuit in parallel with any following telephone which isreceiving an order; but when the circuitchanger of any loop is sopositioned as to fully connect its associated telephone with theorder-circuit itis also so placed as to sever all of the following loopsof the group and their telephones from said order-circuit. Thus theoperators telephones of the group when there is no business going on mayeach and all have their switches so positioned as to connect the saidtelephones with the order-circuit when all preceding ones aredisconnected and so as to sever all following ones. They are thus inline on the order-circuit waiting for orders, and as each precedingoperator receives an order and disconnects to carry out the same thenext following operator is switched in and takes the next order. Havingfully attended to the order, each operator switches back to theorder-circuit, first mov-' ing her switch to the bridge position tolisten and ascertain whether at that moment any other operator isreceiving an order, and if such is the case refraining from bringing theswitch back to the full connecting position until the said order isfully given. It may occur that all of the operators of a grou havereceived orders and are all disconnected from the order-circuit andengaged in completing the connections asked for. To give each callwireaccess under such conditions to other operators, continuation conductorsextend from the separable contacts of the last switching device ofagroup to the main conductors of some one of the other order-circuitsentering the toll-station from other central stations, and so that allgroups may have like extension facilities like continuation conductorsmay be extended from the separable contact of the last switch of thelast group back to the main conductors of the order-circuit primarilyserving the first group. By these means an operator to receive orderscan at all times be reached on all order-circuits.

In the drawings which accompany this specification, Figure 1 is aschematic diagram of an exchange system comprising several centralstations to each of which substation-lines converge and having also atoll-station, whereat trunk-lines leading from the said central stationmay be united with toll-lines leading to the central station of anotherexchange systern. Fig. 2 is a diagram of the toll-station terminalconnections for three order or in stru'ction circuits entering fromthree central stations, representing the essential features of theinvention, the operators telephones, their respective loops, theirswitches, and separable contacts being fully carried out in the firstgroup of five operators positions and indicated in the other two groups.Fig. 3 represents a form of switch or circuitchanger convenient for usein association with the telephone-loops and the order-wire.

In the drawings, and referring now particularly to Fig. 1, E representsa telephoneexchange comprising a number of central stations X Y Z, and EE are other and outlying telephone exchanges having one or more centralstations, as the case may be.

S represents the subscribers stations of the centralstationX of exchangeE, and S S the substations of the distant exchanges E E.

L L L are substation-circuits uniting the stations S to the centralstation X. L L are lines similarly converging from substations S to thecentral station of exchange E and L a circuit connecting substation Swith its appropriate central station atE W is a toll-switching stationof exchange E and may be a separate room in the same building as one ofthe central stations or in a separate portion of a central station, orindeed at any preferred placesuch, for instance, as a building separatefrom any of the other stations. I

It has not seemed necessary to indicate the substation-circuitsconverging to central stations Y and Z; but it is of course to beunderstood that each of these has its quota of substations andsubstation-circuits arranged in the same manner as those of centralstation X.

At central station X, A is the general or answering switchboard, thelines shown as having jacks or switch-sockets at different operatorspositions,and Bis the trunk-board,where also the said lines arerepresented by a switchsocket and where they may be united by suitabletrunk-circuits F F to the switchboard O at the toll office or station W.The said trunkcircuits F F are preferably fitted with switchplugs P atthe central-station end and terminate in sockets J 2 at thetoll-boardend, these, if desired, being multiplied to the several operatorspositions of the board 0., As many of these trunk-circuits are providedas are necessary for the proper conduct of the business.

G G are toll-lines extending from the tollstation W to the outlyingexchanges E and E respectively, and provided or associated at both endswith suitable switching devices, (shown at W as switch-sockets.) Twoclasses of order or instruction circuits are ordinarily employed in sucha general system as this between t-he several central stations and thecommon toll board or room. These are the circuits M M M leading from thecentral stations X Y Z, respectively, over which the answering operatorsat the general s witchboards A transmit orders for toll service to thetoll operators, and the circuits N, extending between the toll-room andthe trunk-boards B at the central stations, over which the toll operatorwho has received an order may repeat it back to B, to the end that the Boperator may assign a disengaged trunk-line and connect the same withthe B board switchsocket j of the line originating the call. It is withthe order or instruction circuits M of the former type that my presentinvention is in particular concerned.

T T T represent the telephone outfits of the call receiving or answeringoperators at the several sections of the general switchboard A, T atswitchboard B represents the telephone of the trunk operator and is inthe order-circuit N to constantly listen for communications from thetoll operator at W, and t t 25 represent the telephones of the severalgroups of toll operators at the toll-station normally associated withthe instruction-circuits M to receive toll-orders, but transferable atthe will of said operators to any other circuits with which they becomeconcerned in the transaction of business for instance, theorder-circuits N or the toll-lines leading to other exchanges. Thetelephone instruments T of the operators at the general board A are ofcourse associated in a manner well known in the art 7 with standardswitch devices, whereby they may be switched about as required from onecircuit to another, and their capability of being switched into theinstruction-circuits M is indicated for the outfit of the severaloperators by the switches s.

The arrangement of the toll-operators telephones tat the toll-board, asindicated in Fig. 1, is symbolic only, the same being shown in detail byFig. 2, to which reference will now be made.

Theinstruction-circuits M M M are shown here as being respectivelyassociated with a such a case the invention would be employed a in itssimplest form, while under other conditions a greater number than fivefor any particular instruction-circuit may temporarily be required, andfor this the invention makes provision, as will be hereinafterexplained.

Q, Q and Q represent loops, in which the operators telephones of thegroups 0 O O are respectively connected, and the contactpoints 0 0 and mm are double terminals of the said loops, m and o branching from oneswitch well adapted to such a purpose.

terminal of the telephone instruments and m o from the other. Associatedwith each telephone-loop Q are terminal contacts g g and h 7L2 of thecorresponding instruction-circuit, these also being in parallel, g and7t branching from the point 1* on one conductor of said circuit and g hbranching from r on the other conductor thereof, and in a mannerpresently to be described the circuit-terminals g g h it may makecontact with the loop-terminals o 0 m 171*, respectively, or bedisconnected therefrom. The circuit-terminals g g of the loops Q, arealso provided with alternative separable contacts 01. n connecting bycontinuation-conductors 2 with the two sets of circuit-terminals g g andh h of the next telephone. It is obvious that in any case where theremight be but two telephones in a group, and if one group only has to beconsidered, the circuit-terminals g 9 associated with the firsttelephone-loop, would alone require the alternative separable contacts gg ,as these are required merely for the extension of theinstruction-circuit from one loop to another and to insure thatfollowing loops shall be severed therefrom when any particular telephoneis in active connection with the circuit.

I provide for each loop Q, and for the telephone 1. contained therein acircuit-changer or switching device H, controlling the terminals of theinstruction-circuit, the telephoneloop, and the continuation of saidcircuit to the next telephone-loop, the said switching device being soorganized as to be capable of being placed in three distinct positions,thereby establishing three different relations of the said terminals andthe circuits to which they belong. In Fig. 3 is shown a form of Astherein indicated, the circuit-changer II is provided with a hand-leverK, fulcrumed at e and having at its inner end a spherical expansionf. Inline with the said expansion in either direction are pairs of springs gg h 76*, adapted to rest by their own resiliency on inner contact stopsor springs n n 171 m respectively. Outer contact-stops 0 0 are alsoarranged,with which the terminal springs g g are adapted to engage whenforced apart. These springs and stops, it will be seen, constitute,respectively, the two sets of circuitterminals, the two sets ofloop-terminals, and the contact-terminals of the continuation-comductors of the circuit. By moving the handle K of the switch to theright the sphere f thereof moves between the ends of the terminalsprings g 9 which thereupon are separated from the contacts at n of thecircuit extension and are brought into contact with the loop-terminals o0 In this position of the switch of any loop the extension of theinstruction-circuitsay Mto all following loops is severed, and theoperators telephone of the said loop is introduced directly into saidcircuit. By moving the hand-lever K to the left the spherical expansionis brought between the terminal springs 7b 71/ and separates them morewidely from one another. They are thus caused to separate from theloop-terminals m m In this position the telephone associated with theswitch is totally disconnected from the instruction-cit cuit, and as thecircuit-terminals g g rest on their front contacts n n the saidinstructioncircuit is continued to the next member of the group, who canreceive orders from it. The circuit-changer is shown in Fig. 3 asoccupying its third or central position, wherein both sets ofcircuit-terminals are permitted to rest on their inner contacts. In thisposition the associated telephone-loop Q is bridged across the circuitby the contact between the circuit-terminals h 72/ and theloop-terminals m m while at the same time the said circuit extension tofollowing telephones remains unbroken in the switch, whose lever is inits central position, by reason of the contact existing between thecircuit-terminals g g and the extension-terminals 02 n When the lever isin this position, by listening at the bridged telephone the operator mayascertain whether any other operator is taking an order from thecircuit. If so, she Waits until the conclusion of said order. If not,she at once moves her switching device to the first position, hertelephone again taking its place directly in the circuit, and allfollowing telephonesbeingcutoff. Theorder-circuitM thus comes directlyto the terminals 9 g of the first member of the first group O and fromthence is extended by continuation-conductors 2 to the last member ofsaid group through the separable contacts g n and g n of the severalmembers of said group, and there is thus constituted an order orinstruction circuit having a group of receiving-telephones, each ofwhich when connected in such circuit cuts off any which follow or arebeyond, so that when the circuit is at rest and all of thetelephone-switches are in position to connect their telephones therewiththey will come into active employment in the order of their relativeprecedence, each operator as she receives an order and switches hertelephone out to execute it giving place to the next in line.

The illustrations of the circuit-changers and theirconnections for thesecond, third, fourth, and fifth members of group O and the second,third, and fourth members of group 0 have not been carried out in Fig.2; but their positions are indicated by stars.

It will be seen that the contacts at n of the last member of group O areshown as being united by continnation-conductors 4 to the mainconductors of the instruction-circuit M at the first member of theprimary group O of said circuit and that the contacts n n of the lastmember of the group O are in like manner united by furthercontinuation-conductors 5 to the main conductors of theinstruction-circuit M at the first member Q of its primary group 0 also,that the contacts 12 n of the last member of group O are united mainconductors of the first instruction-circuit M at points o 12 By theseexpedients the several central Stations X Y Z can each (if all of theoperators of their own primary groups are busy) transmit orders to theseveral operators in succession of the other groups, all groups beingthusmade available on emergency to all order-circuits. Thus the businessoriginating at the several central stations may be divided as evenly aspossible among the three groups during the busiest hour of the day andduring the less busy hours may be put upon the circuits of one or twogroups, or the number of operators in each group may be lessened. Anyoperator receiving an order at once throws the circuitchanger to theposition indicated for the first member of the first group O,disconnecting her telephone from the order-circuit, and then proceeds todo all of the work required in the execution of the order until thestation giv-r ing the call at X for a station of the distant exchange Ehas obtained through communication and does not threw her switch overand reconnect with the instruction-circuit until this is done. When No.1 telephone is thus disconnected, No. 2 becomes first, and when No. 2receives an order No. 3 succeeds, and so on through the groups. No.2 ofgroup O and No.5 of group O are shown as having their switches sopositioned as to fully connect their telephones with their respectiveinstruction-circuits. No. 1 of group 0 has the switch placed todisconnect its own telephone, leaving the circuit connected with No. 2,and the remaining switches are shown as occupying the middle position,so that their telephones are in the bridge positions, where theoperators can listen in at their respective circuits Without severingthe connection of said circuits to following loops. The electricalconnections of the five members of the group 0 are all shown in full,comprising the telephone-loops, the telephones connected therein,theswitclrcontacts, and the mode of carrying out the extension of theorder-circuit through the several sets of separable contacts in series,and as each group is constructed and arranged on the same general planit will be understood that while the first member only of group O andthe first and fifth'members only of group O are shown the other members,which are merely indicated, are to be connected precisely as those ofgroup O.

In describing the operation of the system we may assume that Xrepresents the main central station at Chicago and that E represents theoutlying city of Evanston. No. 144 main wishes to connect and talk withNo. 27 Evanston. 144 calls and his call is received by the answeringoperator at the regular switchboard A. Being informed that 144 wants atoll connection, the operator at A connects a telephone T with theinstructioncircuit M and transfers the order to any to11- room operatorwho happens to be first in line,

saying, for example, 144 wants a toll connection. The toll operator,hearing this, at once moves over her switch H to the position shown attelephone No. 1 of group 0, thus disconnecting her telephone from theinstruction-circuit and causing the said circuit to be extended to thenext following operator of the group. By means of the usual switchapparatus she connects with the return ordercircuit N and asks theoperator at the trunkboard to connect 144 main to a trunk-circuit. Bdoes so and says 144 is connectedto trunk F. This brings substation 144main into direct communication with the toll operator, who at oncereceives the details of the order, enters the same on a ticket, andhaving a switch-socket J of the toll-lines in front of her proceeds tosignal and advise Evanston of the number wanted and complete the con- InFig. 1 substation 144 main of nection. Exchange E is shown as beingconnected through with substation 27 of Exchange E by means of theswitchboard 70, forming the terminal at trunk-board of the trunk-line F,the switch-cord k uniting the toll-board terminal of said trunk with thetoll-line G and the switch-cord k of board D at Exchange E uniting the Eend of the toll-line to the substation-circuitL. The toll operator No. 1having thus fully attended to the call and having supervised the sameuntil the foregoing connection has been completely established returnsher telephone to the instruction-circuit, first placing the switch H atthe middle position to listen, so as not to interrupt any order which isbeing at the moment transmitted. Hearing nothing, the telephone isbrought directly into the circuit and No. 1 again has the first place,all of the following ones being cut off. Meanwhile the second,third, andall following telephones of the group may successively have been firstin line and may have received and attended to toll-calls, and it mayalso have happened that all of the primary telephones of agroup havingreceived an order and having disconnected from theirinstruction-circuits to attend to it some telephone on the next or thirdgroup'has become the first in line on the said circuit and receives anorder or call therefrom.

The invention is of course not restricted to cases where a trunk-board Band trunk-lines extending therefrom intervene between the callingsubstationline and the toll-line, it being obviously adapted equallywell for systems wherein switch-sockets of the exchange lines are placeddirectly in the toll-room, dispensing with such intermediateconnections.

By this invention the order or call, the making and handling of theticket, and the toll switch connections are all under the charge of asingle operator, there is no passin g of tickets by machinery orotherwise from one operator to another, and the number of operators mayat any time of the day be readily proportioned to the amount of workpresenting itself.

Havin g thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a telephone-exchange switching-station, thecombination of an order or instruction circuit; two loops therefor, eachcontaining a separate receiving-telephone; and a three-positioncircuit-changer or switch at the junction of said circuit and loopsadapted to unite either telephone-loop alone, or both at once inparallel to said order-circuit, according to the position in which itmay be placed.
